• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) or (sach thieu)) ((nang xa) OR (lang xa)) hoi. hieu va nam xuc va hanh lai chau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach thieu)) ((nang xa) OR (lang xa)) hoi. hieu va nam xuc va hanh lai chau triet.
